The invention discloses a movie bar and KTV combined processing equipment comprising a movie signal port, a KTV port, an auxiliary port, a sound processing and conversion module, a control device, an audio output port and a power supply circuit. The movie signal port receives an external movie signal and transmits the external movie signal to the sound processing and conversion module. The KTV port receives an external KTV signal and transmits the external KTV signal to the sound processing and conversion module. The auxiliary port receives other external signals apart from the aforementioned signals. The sound processing and conversion module receives the signals transmitted by the movie signal port, the KTV port and the auxiliary port and processes the signals and then transmits the signals to the audio output port. The control device transmits or receives an operation instruction to/from the sound processing and conversion module. The audio output port receives the signals transmitted by the sound processing and conversion module and outputs the signals to the outside. A gating module performs gating on the signals received by the sound processing and conversion module. The sound processing module performs processing according to the sound scene characteristics required by the movie signal port, the KTV port or the auxiliary input port. A scene matching module matches sound scenes with the corresponding input ports and selects the signals to be transmitted to the audio output port.
